I just got this 70s Medici frame on ebay and started collecting components to mount on it. First up, bottom bracket and crankarms.

I found an english thread Campagnolo Daytona BB, thinking it would be a standard size. Lo and behold it's about a mm or two too small in diameter. I've not been able to find much info online about the different BB sizing. Can anyone provide any insight? Greatly appreciated.

Here's the side of the BB:
